It has been a month now and I still can't figure this out. Jobs just stop printing sometimes after one page, sometimes after 10 pages, sometime 50 page jobs will print just fine, sometimes they won't. Each time I have to restart cups and then the job restarts from the beginning. I never had this problem until updating to Fedora 10. Is there anyway to find out what is causing this???
